Neonatal lacrimal sacculitis is common in our clinic, with about 10 cases per day, and sometimes 30 cases. Generally, within one or two months after birth, yellowish-white discharge from the eye is accompanied by lacrimation, and some children are prone to eczema on the external r and face. Sometimes there can be mucous-like clear or yellow discharge out of the tear sac area by pressure. However, the conjunctiva and cornea of the eye are generally good. The tear sac area of the inner r part of the eye is red and swollen during acute attacks and can easily be mistaken for ocular cellulitis. Generally, the traditional textbook gives antibiotic eye drops for conservative treatment, and the tear duct can be explored after 6 months, but there are already hospitals in China that give tear duct exploration at 2 months. Our treatment is conservative until 3 months of age, taking into account the developmental process of the child, and after 3 months and between 1 year of age, lacrimal duct probing (using a non-invasive probing needle) can be performed depending on the situation. After 7 years of clinical observation, probably more than 90% are completely cured and 10% need further surgical treatment. For children with acute episodes, the success rate is personally higher if the lacrimal duct is reopened two to three weeks after the completion of anti-infection treatment.
